Background: Numerical study of angulation effects of renal arteries on blood flow has been of great interest for many researchers.Objective: This paper aims at numerically determining the angulation effects of stenosed renal arteries on blood flow velocity and renal mass flow.Method: An anatomically realistic model of abdominal aorta and renal arteries is reconstructed from CT-scan images and u...

The main cause of ischemic stroke is the atherosclerotic lesions carotid arteries. Unlike other arteries, arteries have unique anatomical structure and hemodynamic characteristics, which are significantly related to occurrence atherosclerosis.
 Thus, a proper understanding functional anatomy, local hemodynamics their relationship with process can improve quality early diagnosis treatment a...

awareness of the presence of the accessory renal artery in kidney transplant, treatment of renal artery stenosis, clinical assessment of renal vascular hypertension, radiology and angiography interventions is very helpful. in 30% of cases the accessory renal artery is separated from the abdominal aorta and in most cases, this artery along with the main artery entered to the kidney through the h...

introduction: the persian squirrel (sciurus anomalus) is considered the only well-known species of the family sciuridae in the middle east. since some people keep this squirrel as a domestic pet, their attendance at veterinary clinics is increasing. so far, no study has been conducted on the arterial supply of the pelvic cavity and limb in the squirrel. hence, this research was performed to fil...

Background: During the first trimester of pregnancy the uterine spiral arteries that supply blood to the placenta are remodelled, creating heavily dilated conduits lacking maternal vasomotor control. To effect permanent vasodilatation, the internal elastic lamina and medial elastic fibres must be degraded. Failure of remodelling is a key characteristic of the pathological placenta and is though...

The basic patterns of the cerebral arteries development are highly conserved across vertebrates. Historical and recent studies based on human embryos, comparative anatomy, angiographies allowed us to better understand embryological arteries. knowledge understanding such important for neurointerventionalists interested in neurovascular diseases, especially stroke, because we may encounter unexpe...

conclusions by measuring image quality metrics, this study showed that dtd and ctd filters with the canny edge detection respectively, are better than srad filter with the canny detection for speckle suppression and details preservation in both arteries in the ultrasound images. background ultrasonic evaluation of intima-media thickness (imt) is an early marker of assessing the development of a...
